The Sea Ray 420 Sedan Bridge 2005 vs Sea Ray 540 Sundancer 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Sea Ray 540 Sundancer 2011 measures 54,8 feet overall (2011), giving it roughly 9,8 additional feet of deck space compared to the Sea Ray 420 Sedan Bridge 2005 at 45,0 feet (2005).

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The Sea Ray 540 Sundancer 2011 tops out at 715 hp. Engine specs for the Sea Ray 420 Sedan Bridge 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 420 Sedan Bridge 2005 carries 35 gallons versus 6 gallons in the Sea Ray 540 Sundancer 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Sea Ray 540 Sundancer 2011 at 54,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 420 Sedan Bridge 2005 at 45,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
